I would very much appreciate some advice on the following nudibranch I found under Portsea Pier [Victoria, Australia]. The specimen was about 50mm(2inches)long, light-medium pink, white globules on the end of a number of appendages on its body and from closer inspection of the slide its body has a texture similar to the pink prickly sponge we have over here.

Your animal is Verconia verconis, a species found only in southern Australia, from Victoria to Western Australia. It is a chromodorid nudibranch with unique papillae along the mantle edge which help it to mimic the shape of the sponge it is usually found on. As you have noticed, the papillae have white glandular structures at their tips which store defensive chemicals which they have obtained from their sponge food.
Have a look at the top of this page, and at the other messages below yours on this page for more information. Also have a look at the page on Nudibranch Defence.
